This question already has an answer here:
When transferring some bitcoin from coinbase to my hardware wallet, I see on coinbase and on my hardware wallet that the amounts sent and received are about the same (minus a transaction fee), as expected. But when I look up the transaction on live.blockcypher.com, the Amount Transacted and the Input Consumed is much larger than the amount I transferred. There are two outputs, one unspent amount matching the amount I transferred minus the fee (and using my hardware wallet address) and one spent amount equal to the difference between the amount transacted and the amount I transferred (using a wallet address I don't recognize). Why is the Amount Transferred larger than the amount I actually transferred? Thank you.
